No, zsh supports NUL bytes in its strings happily. It's even in
the default $IFS. Where NUL bytes can't go, it's in arguments
to commmands, environment variables, filenames... But I can't
see why a shell variable couldn't contain NUL bytes, it's even a
good thing for both those reasons as you can use that character
to safely separate filenames, arguments, env vars... See for
instance the -0 option of many GNU utilities.
